Convection Currents -The container is filled with room temperature water that I left overnight in the container. I use a blue colored ice cube to resemble cold air and Red hot water to how resemble warm air. Genius! You can see the cold blue ice cube immediately starts sinking to the bottom.
The red warm water rises throws the top and the cold blue ice cubes sinks. Same goes for air!
Convection currents happen within the Earth’s magma, water and air. It can happen in anything that is not solid and has parts that are cooler or warmer than other parts
A classic example of a convection current would be that of warm air rising towards the ceiling in a house. That’s why it’s always hotter upstairs. This happens because warm air is less dense than colder air.
